The best security you can get in a web browser!Allow active content to run only from sites you trust, and protect yourself against XSS and Clickjacking attacks, "Spectre", "Meltdown" and other JavaScript exploits.Fx52? https://noscript.net/getit

Winner of the "PC World World Class Award" and bundled with the Tor Browser, NoScript gives you with the best available protection on the web.

It allows JavaScript, Flash, Java and other executable content to run only from trusted domains of your choice, e.g. your home-banking site, mitigating remotely exploitable vulnerabilities including Spectre and Meltdown.

Such a preemptive approach prevents exploitation of security vulnerabilities (known and even unknown!) with no loss of functionality where you need it.Experts do agree: Firefox is really safer with NoScript ;-)
